Event or Problem Description
|
|
The customer contacted stryker to report that their device displays "abnormal energy delivery message." in this state, wrong defibrillation therapy may be delivered to the patient.There was no patient use associated with the reported event.Upon evaluation of the customer's device, stryker observed that the customer¿s device was unable to deliver defibrillation energy.In addition, the device logged an event code in the device's memory that is indicative of a device failure that could result in a partial loss of defibrillator output energy due to a loss of the negative portion of the biphasic output waveform, resulting in a monophasic shock.Additionally, the defibrillator output energy may be reduced by up to approximately 20% from the selected energy level.As a result, the wrong defibrillation therapy would be delivered, if it were necessary.
